Magnetospeed Sporter. What it does and what it does not do. 

Thanks Dave for recommending this video.

Great shooting Dave,I really enjoyed this video,tons of good info that is what I have been curios about,have a good day

Good video. It is nice to see what difference the magneto speed has on POI.

Glad to see you wielding the tried and 25-06 . For many years my go to Wyoming mulie & antelope rifle. Dozens of successful kills,all 1 shot drops.

Thanks Dave, a interesting video and result! My 2c worth is this, the only purpose of the chronograph is, as you said, just to collect data. You could have shot into the side of a hill or not even bothered to get down into the rifle, the data would be the same! The fact that with the magnetospeed attached messes with barrel harmonics, is in this case of no consequence what so ever! All the best from Dorset England 🇬🇧🇺🇸👍

Thank you for explaining the difference between accuracy and precision better than I could. Barrel harmonics are a little bit of magic. I bought a Savage mark 2 to compete in my local rimfire match. I played with a shaft locking collar on the barrel and I was being very competitive and winning some matches against guys shooting $1500+ rifles. To boot I was using $6 tac22 and they are using expensive match ammo. It is a great way to spend a Sunday afternoon.

Very enjoyable video. Some thought, a barrel tunner is about the same weight and proven to affect group size of a well developed load. Anything weighing down the muzzle will act the same way. From the manufacturer, they recommend to load develope without it then use it to verify velocities. I too have seen it both not affect accuracy and also drastically effect accuracy. For what I do, a 100$ Wiser Precision mount is an easy buy. Set's up faster and eliminates the question

You Sir, are telling it like it is. And, You ARE Correct. It's weird how people think and what they get into their heads. I think You are about like I am. I can see you take care of Your stuff. There ain't a scratch on that rifle. I used to shop at Hogdon Powder store South of Kansas City. I'd buy alot of my reloading supplies from them back then. I'm thinking of trying to get one of those Magnetospeed units for my use I can't see 600+ dollars for some of those other units on the market. Another GREAT JOB on this video too.

Dave, Good video and explanation. As always nice shooting. Take care.

Good video Dave I understand completely but like you said it will get mixed up on some sites but I think 🤔 you set them straight thanks

Thank you Dave, you proved my point exactly. The bayonet attached to the barrel affects the harmonics and therefore affects the point of impact. But like you said if you are not concerned with where your shots are hitting it makes no difference. You can adjust your shot groups to hit your target with the scope. I just prefer a stand alone chronograph that does not have an effect on the harmonics or the point of impact. It saves time, money, ammo, and money not having to sight in twice. But that's why they make both chocolate and vanilla, people like different things. Just because methods are different does not make one of them wrong. I enjoy your videos keep up the good work. You are appreciated. Kindest Regards,

I run a 25-06 as well. It does a fine job on whitetails. Just picked up this chronograph. It's small, easy and I can stay under cover if it's raining.

I too have a magnetospeed sporter to get velocity data. When I do my load works up, I generally dont care about velocity. I am looking for the tightest group I can get. Once I have that then I load some validation loads and then put the magnetospeed on and get velocity data.

Great video Dave , i don't own a Chronograph but still load and shoot for tight groups and then once I've found what's good for me , "Accuracy ".... Can you show us your shooting bench set up one day , would be interesting to see close up .

The POI difference with the Sierras was drastic. We've had smoke like that too, here in The Bakken.

The chrono may change the P.O.I. but you get the speed with it on then test for the accuracy with it off. If you have a problem with that buy the doppler radar.

What do you think of the labradar? I know they are quite expensive over $500 but caldwell is supposedly going to release a similar product for around $300, i have used a labradar and once the trigger mech is installed it works like a charm

BBR's load slick as glass

Hey good job I like your video you made the point of difference of in grains change of bullets and grouping ,what was the rifle make very nice.

God bless you too Dave. I use the magnetospeed as well . Is your barrel floated ? Mine has the pressure point ( weatherby wilderness 2506) struggling with finding an accurate factory load so I floated the barrel but still not going well. Decided on barnes 100 grain. Cold bore shot is right on 1 1/2 inch high at 100 but second and third shots start climbing up to 2 1/2 to 3 inches so I added the pressure point back to see if it would help, wanted to shoot again today but is raining. We get rain here lol

Beautiful rifle in an awesome caliber, I am a Browning fan myself. Which scope is on it? Good shooting

I used my sporter to get velocity of ammunition to be able to calculate ballistic drop of 300 m and 350 m and 100 m. For my 30.06 is zero for 200 m. I have recently made some reloads of 4 different weight that would achieve minimum of 2800 fps to max of 2900 fps. I also use IR gun measure barrel temperature what wait 5 minutes per each shot and 15 minutes after reloading. I want to see which load gives tightest group within desired velocity range so I can reload. Then zero scope with ammunition that gave best consistency. Reason I am doing this someone I have to take 300 m shot. Most of time within 100 to 200 m, and occasionally at 300 m.

Dave, nice shooting. With this data, would you switch from Nozzler or would you run a few more test loads?

Do you find that the magnetospeed is effected by weather (bright sunny, overcast) where it will not record under certain conditions?

I want a chrono to get the velocity of the loads, not shooting groups. The chronograph is not for measuring groups, that's what calipers are for. Just like when I'm hunting, I'm probably not going to be shooting from a covered bench off of a bipod or sandbags only when the weather suits me.

Dave, thanks. Were these factory or reloads? You gave averages, but what about SD and ES? BTW I enjoyed your rock chuck hunting videos.

Have you ever use rifle barrel limbsaver on your rifles?

25-06 in a odd round dont see to much of them anymore?

I think it's safe to say your gun likes hornadys

It's time for a new barrel Dave. That thing is shot out

Damn time to buy a tikka

Doubt you see this but if you do you are pronouncing hornady right. Raised in gi Nebraska where the plant is. That being said I do still hate their products. While they are pin point accurate I have seen way to many fail on impact and will not recommend any of their products for hunting.
